Typhoon is a minimal and free Kubernetes distribution.
2017-08-07 08:49:05 +02:00
* Minimal, stable base Kubernetes distribution
2017-07-25 07:12:13 +02:00
* Declarative infrastructure and configuration
2017-08-23 09:44:38 +02:00
* [Free ](#social-contract ) (freedom and cost) and privacy-respecting
* Practical for labs, datacenters, and clouds
2017-08-07 08:49:05 +02:00
2017-08-28 01:09:23 +02:00
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
2017-08-07 08:49:05 +02:00
## Features
2017-10-04 05:48:24 +02:00
* Kubernetes v1.7.7 (upstream, via [kubernetes-incubator/bootkube ](https://github.com/kubernetes-incubator/bootkube ))
2017-09-18 07:50:55 +02:00
* Single or multi-master, workloads isolated on workers, [Calico ](https://www.projectcalico.org/ ) or [flannel ](https://github.com/coreos/flannel ) networking
2017-09-08 22:56:20 +02:00
* On-cluster etcd with TLS, [RBAC ](https://kubernetes.io/docs/admin/authorization/rbac/ )-enabled, [network policy ](https://kubernetes.io/docs/concepts/services-networking/network-policies/ )
* Ready for Ingress, Dashboards, Metrics, and other optional [addons ](https://typhoon.psdn.io/addons/overview/ )

## Example
Define a Kubernetes cluster by using the Terraform module for your chosen platform and operating system. Here's a minimal example:
```tf
2017-08-28 01:09:23 +02:00
module "google-cloud-yavin" {
2017-08-23 09:44:38 +02:00
source = "git::https://github.com/poseidon/typhoon//google-cloud/container-linux/kubernetes"
# Google Cloud
2017-08-28 01:09:23 +02:00
zone = "us-central1-c"
dns_zone = "example.com"
dns_zone_name = "example-zone"
os_image = "coreos-stable-1465-6-0-v20170817"
2017-08-23 09:44:38 +02:00
cluster_name = "yavin"
controller_count = 1
2017-08-25 09:14:02 +02:00
worker_count = 2
2017-08-28 01:09:23 +02:00
ssh_authorized_key = "ssh-rsa AAAAB3Nz..."
2017-08-23 09:44:38 +02:00
# output assets dir
asset_dir = "/home/user/.secrets/clusters/yavin"
}
```
Fetch modules, plan the changes to be made, and apply the changes.
```sh
2017-09-23 22:02:18 +02:00
$ terraform init
2017-08-23 09:44:38 +02:00
$ terraform get --update
$ terraform plan
Plan: 37 to add, 0 to change, 0 to destroy.
$ terraform apply
Apply complete! Resources: 37 added, 0 changed, 0 destroyed.
```
In 5-10 minutes (varies by platform), the cluster will be ready. This Google Cloud example creates a `yavin.example.com` DNS record to resolve to a network load balancer across controller nodes.
```sh
$ KUBECONFIG=/home/user/.secrets/clusters/yavin/auth/kubeconfig
$ kubectl get nodes
2017-08-28 01:09:23 +02:00
NAME STATUS AGE VERSION
2017-10-04 05:48:24 +02:00
yavin-controller-1682.c.example-com.internal Ready 6m v1.7.7+coreos.0
yavin-worker-jrbf.c.example-com.internal Ready 5m v1.7.7+coreos.0
yavin-worker-mzdm.c.example-com.internal Ready 5m v1.7.7+coreos.0
2017-08-23 09:44:38 +02:00
```
2017-08-28 01:09:23 +02:00
List the pods.
```
$ kubectl get pods --all-namespaces

## Non-Goals
2017-08-07 08:49:05 +02:00
2017-08-23 09:44:38 +02:00
Typhoon is strict about minimalism, maturity, and scope. These are not in scope:
2017-08-07 08:49:05 +02:00
2017-08-23 09:44:38 +02:00
* In-place Kubernetes Upgrades
* Adding every possible option
* Openstack or Mesos platforms

## Background
2017-08-07 08:49:05 +02:00
2017-08-28 01:09:23 +02:00
Typhoon powers the author's cloud and colocation clusters. The project has evolved through operational experience and Kubernetes changes. Typhoon is shared under a free license to allow others to use the work freely and contribute to its upkeep.
2017-08-07 08:49:05 +02:00
2017-08-28 01:09:23 +02:00
Typhoon addresses real world needs, which you may share. It is honest about limitations or areas that aren't mature yet. It avoids buzzword bingo and hype. It does not aim to be the one-solution-fits-all distro. An ecosystem of free (or enterprise) Kubernetes distros is healthy.

## Social Contract

2017-08-28 01:09:23 +02:00
Typhoon is not a product, trial, or free-tier. It is not run by a company, does not offer support or services, and does not accept or make any money. It is not associated with any operating system or platform vendor.
2017-07-25 07:12:13 +02:00
2017-08-23 09:44:38 +02:00
Typhoon clusters will contain only [free ](https://www.debian.org/intro/free ) components. Cluster components will not collect data on users without their permission.
